BACKGROUND:The massive transfusion protocol (MTP) is designed to quickly provide blood products at a fixed ratio for the exsanguinating patient. At our academic medical center, the frequency of MTP activation increased over 10-fold between 2008 and 2015, putting inordinate stress on our transfusion service.STUDY DESIGN AND METHODS:Gathering a large number of relevant stakeholders, we performed a multidisciplinary root cause analysis (RCA) in response to the acute clinical need to reform our MTP.RESULTS:Through the RCA, we identified four principal opportunities for improvement (OFI) associated with our MTP: education, stewardship, process improvement, and communication. Through the deployment of new approaches to each of these OFI, we reduced MTP activations, blood product waste, and transfusion service technologist stress.CONCLUSION:The MTP is amenable to improvement, and, although time intensive, the RCA process yields significant favorable effects: improving communication with colleagues, reducing stress within the transfusion service, and improving resource utilization. Activation of the MTP at our institution is now more aligned with its primary purpose: rapidly providing large quantities of blood products to exsanguinating patients.

BACKGROUND:The objectives of this time-series study were to elucidate the impact of a thawed plasma standard operating procedure (TP SOP) on plasma wastage and on cost savings.STUDY DESIGN AND METHODS:This study compared plasma wastage for 1 year before versus 1 year after implementation of a TP SOP.RESULTS:The plasma wastage and discard declined 79.7 and 64.9%, respectively, with a cost savings of $15,654.79 during the 1 year after implementation of the TP SOP. The risk that a unit of plasma would be wasted decreased 86.2% from Year 1 to Year 2 and the risk that a unit of plasma would be discarded decreased 76.3% from Year 1 to Year 2.CONCLUSION:Our study showed the positive, sustained, impact of implementing a TP SOP. Twelve months after introducing the SOP our Blood Bank and Transfusion Medicine Services' plasma wastage and discard were dramatically reduced, saving thousands of dollars. Initiating a TP SOP just makes sense; it is easy to implement, conserves plasma, and saves cents.

BACKGROUND: Three women have been identified with an antibody to a "new" high-incidence antigen found on multiple cell lines.CASE REPORTS: The proposita, M.A.M., presented during her third pregnancy with an antibody reacting with all RBCs tested except her own. She delivered a thrombocytopenic infant with a 3+ DAT, but without symptoms of HDN. The second example, A.N., presented during her third pregnancy with an antibody reacting with all RBCs tested except her own and those of M.A.M. She delivered a slightly thrombocytopenic but severely anemic infant. The third example, F.K., a sister of A.N., has an antibody reacting with all RBCs tested except her own and those of M.A.M. and A.N.CONCLUSION: This "new" high-incidence antigen has been named MAM and assigned high-incidence antigen number 901016 by the International Society of Blood Transfusion. The corresponding antibody, anti-MAM, has been shown to cause HDN and has the potential to shorten RBC survival after the transfusion of incompatible RBC units, as determined by monocyte monolayer assay. Immunoblotting and flow cytometry show that this new antibody reacts with various WBC lines in addition to RBCs. This antibody also appears to react with platelets in some assays.
